IMPROVEMENT IN MOLDS FOR MAKING GLASS BLlND-SLATS.

Specification forming part of Letters Patent No. 136,835, dated March18, 1873.

To all whom it may concern:

Be it known that I, ELIAS B. HUNGERFORD, of Corning, inthe county ofSteuben and State of New York, have invented certain new and usefulImprovements in Molds Setting and the Application of Wire Staples inGlass Slats for Blinds and Shutters; and the following is a full, clear,and exact description of the same, reference beinghad to theaccompanying drawing making a part of this specification, in which' v vFigure 1 representsa top view of a mold, in which glass blind-slats areformed by pressing the glass into them, closed. Fig. 2 is a perspectiveview of the mold open showing the wire staple as set in the base to besecured to the slat; also the plunger to compress the glass slat'firmlyaround it. Fig. 3 shows a cross-section of the mold and base with anedge view of the staple set in it. p

The obj ect and nature of my invention are an improvement on the glassblind-slats, for which Letters Patent were granted to me February 27,1866; and it consists in the attaching wire staples firmly to the slatmade of glass, and the arrangement of the mold to set and hold thestaple in a firm position so that the glass will be pressed around it,andwhen removed from the mold is secured in the edge.

The mold A A is made of metal, and hinged to open in the usual manner,having in each half the impress of the form of the slat a a, the samebeing provided with a recess, 1) b,

above, in which is fitted a plunger, B, to force the plastic glass intothe form a a, and corn press it firmly around the wire staple c, whichis set in a recess, 6, made in the base-block D for the purpose, andheld firmly in a vertical position by closing the two sides of the moldA A onto it. When the slat is removed from themold, the staple is firmlyset in each glass blind-slat, so that a series of them are connected bya rod, to operate the same as movmy name. E. B. HUNGERFORD.
